How to install and build C++ gRPC

Here are the official instructions for downloading and building grpc

However, the following is a more relevant version of how grpc was installed on the ejfat nodes

Setup some environmental variables (assuming bash)

export GRPC_INSTALL_DIR=/daqfs/gRPC/installation
export PATH="$GRPC_INSTALL_DIR/bin:$PATH"
export LD_LIBRARY_PATH="$GRPC_INSTALL_DIR/lib:$LD_LIBRARY_PATH"

The alternative is to run a provided bash setup script which does the same thing

/daqfs/gRPC/setupgrpc

Clone the repository

git clone --recurse-submodules -b v1.50 --depth 1 --shallow-submodules https://github.com/grpc/grpc

Build the package

cd grpc
mkdir -p cmake/build
pushd cmake/build
cmake -DgRPC_INSTALL=ON -DgRPC_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=$GRPC_INSTALL_DIR -DBUILD_SHARED_LIBS=ON ../..
make -j 4
make install
popd

Currently grpc is installed in /daqfs/gRPC/
